How to take an image of the internal memory of an android tablet to a file?

Question

Android

Hello.

I deleted some files on the tablet, I want to restore them.
There was no SD card on the tablet, so all data was saved to internal memory. The device is not rooted.
I want to take a disk image and use known methods to search for and restore files.

I just can't figure out how to take a disk image.
The idea is this: root the tablet, then insert the SD card and remove the image through the terminal with the dd command, but maybe there are simpler solutions?

Answer 1

Solution:
1. We get the root.
2. Run adb.exe from the Android SDK for windows, (turn on USB debugging)
3. write in the console:

su
dd id=/dev/block/mmcblk0 of=/Removable/MicroSD/bacup.iso

(The SD card can be mounted elsewhere)
And then the disk image is recognized as a regular Ext4 (for example, on a PC3000)

Answer 2

Only root, well, or soldering a memory chip, which is clearly more difficult.

Answer 3

I wonder what kind of critical files you could delete on an unrooted tablet? Maybe it's easier to roll the firmware again?

And if there are no CD cards in the phone, for example lenovo! So where to point the way?
